【摘要】：近年来,移动互联网的日益繁荣,移动应用软件的数量迅速增多。Android平台成为移动应用最多、用户数量最大的平台之一。同时,面临的安全威胁也日益严重。应用软件容易被破解和篡改,植入广告和恶意代码,并通过各种第三方渠道肆意传播,严重损害了互联网企业和广大用户的权益。移动应用软件的安全保护研究具有极大的现实意义。鉴于Android平台应用软件安全的重要性,本文对Android操作系统的安全机制和应用软件所面临的威胁进行了分析。重点论述和分析了现有的Android应用软件保护技术,包括源代码保护技术、反篡改技术、加壳技术、文件隐藏技术、反调试技术、反模拟器技术。并将各种保护技术结合起来,设计了综合的保护方案。其中,反模拟器技术环节较为薄弱,但又极为重要。因此,本文将反模拟器技术作为研究的重点。在反模拟器技术方面,分别对现有的几种反模拟技术和模拟器隐藏技术进行了详述和分析。进行了反模拟器技术与模拟器隐藏技术的攻防实战。通过对实验结果进行分析,本文提出一个基于波动信号量的异常检测技术。该技术运用异常检测的思路,结合Android平台的特点,实现了对模拟器的检测。基于波动信号量的异常检测技术准确度高、扩展性好、具有较强的实际应用价值。
[Abstract]:In recent years, with the increasing prosperity of the mobile Internet, the number of mobile applications has increased rapidly. Android platform has become one of the most mobile applications and the largest number of users. At the same time, the security threats are becoming more and more serious. Application software is easy to be cracked and tampered with, advertisement and malicious code are implanted, and spread wantonly through various third-party channels, which seriously damages the rights and interests of Internet enterprises and users. The research on security protection of mobile application software is of great practical significance. In view of the importance of application software security in Android platform, this paper analyzes the security mechanism of Android operating system and the threats to the application software. This paper mainly discusses and analyzes the existing Android application software protection technology, including source code protection technology, anti-tamper technology, shell technology, file hiding technology, anti-debugging technology, anti-simulator technology. Combined with various protection technologies, a comprehensive protection scheme is designed. Among them, the technical link of counter-simulator is relatively weak, but extremely important. Therefore, this paper focuses on counter-simulator technology. In the aspect of counter-simulator technology, several existing anti-simulation techniques and simulator hiding techniques are described and analyzed in detail. The anti-simulator technology and the anti-simulator hiding technology are carried out in the attack and defense. By analyzing the experimental results, an anomaly detection technique based on fluctuation signal is proposed in this paper. This technique uses the idea of anomaly detection and combines the characteristics of Android platform to realize the detection of simulator. The anomaly detection technology based on fluctuation signal has high accuracy and good expansibility, and has strong practical application value.
